Firstly, yes Diesel (AVTUR) will both burn and explode. The conditions to make it explode are a little harder to achieve than with petroleum spirit (AVGAS) but it's do-able, so a Diesel fuel system is no particular life-saver.
I would have quoted that as much harder hence you very rarely hear of a diesel bomb.
Very good advice Genghis now can you advise on the carb post and if a C152 needs engineering attention after a carb fire.
